I have my second HCA blood test coming up next week but I can't remember if I have to fast for this one?
Does anyone know?
My first one was back in June, so a long time to recall what I had to do.
I know it's a 9 0'clock appointment, so if I do need to fast it won't be too bad.
Thanks in advance

I'm pretty sure you'll have to fast 10-12 hours but a quick call to your surgery should make it all 99% clear !! Good luck hope you get the results you want

No, an HbA1c test does not require fasting - it is an average of the previous 2 to 3 months so what you have just eaten will have no effect.

However, we normally also have other tests at the same time, one of which is the cholesterol. In order to get an accurate Triglyceride reading you do need to fast, otherwise your triglycerides will be swimming all round your blood stream doing their job and will thus give a higher reading.
